Cache Compatibility
The WGM cache compatibility eliminates the need to upload all files before Windchill server upgrade. The cache can always be retained and is compatible after upgrading or updating the Windchill server.
The WGM cache contents are based on how the WGM client (that is, Creo or WWGM) communicates with the current version of the Windchill server. The possible communication protocol is controlled by the client version being used. The WGM client may communicate in an older cache format when connected to an older Windchill server version or in a newer format when connected to the latest server version. These communication protocol changes required the WGM cache to be deleted and recreated in earlier versions of WGM Client. PTC also recommended uploading all local files before performing a Windchill upgrade or WGM client upgrade.
Starting with Creo Parametric 9.0, PTC supports WGM cache compatibility for each Creo MOR and major versions with all its supported Windchill versions. This eliminates the need to upload, delete, and recreate WGM cache.
Similarly, starting with WWGM 12.1.2.0, PTC supports WGM cache compatibility for each new WWGM version and major versions with all its supported Windchill versions.
Additionally, starting from Windchill 12.0.2, Windchill upgrade supports WGM cache compatibility for Creo 9.0 and WWGM 12.1.2 and above.
If your company is using a WGM version older than Creo Parametric 9.0 or WWGM 12.1.2, cache compatibility will not be supported during Windchill upgrade. Local CAD documents in workspace should be uploaded before Windchill upgrade if you want to create the cache after upgrade.
Caveats:
• WGM Cache compatibility during WGM upgrade and Windchill upgrade is supported within the supported PTC compatibility matrix. For more information about compatibility, see:
• Running Creo with WGM cache generated in higher Creo Parametric version is not supported. If you have multiple major versions of Creo that is Creo Parametric 9.0 and Creo Parametric 10.0) for the same user on the same machine, you cannot use the same cache for both Creo versions. To benefit from these changes, you must have different caches for each major Creo version. For more information about how to configure Creo Parametric to use different caches, see this Article CS44499.
• Running WWGM with WGM cache generated in higher WWGM versions is not supported. If you use multiple versions of WWGM for the same user on the same machine, you cannot use the same cache for all WWGM versions. To benefit from these changes, use different caches for each major WWGM version. For more information about how to configure WWGM to use different caches, see the Article CS212589.
